These are basic standard police handcuffs plain and simple. they can be used for bedroom action to spice the night up or they can be a secondary set of cuffs for multiple arrests if you're indeed an officer of the law.

These guys are made of solid metal with moving parts. There is no escape button like there is on a lot of them. Most toys are fakers. They come with 2 sets of keys. I suggest to put one on the car ring and the other in a bedroom cabinet or something, so if you misplace one then you can fall back on the other set.

Awe, here is where personal experience comes in. I can say that having been cuffed both from behind and in front, the metal is cold unless they've been warmed up by something. They are heavy, but pleasingly so. They can be connected to a hook, that is connected in a wall/headboard, or chained through a fence. Bruising? I don't mind it. It shows people I've had a really good time, just like I can run my fingers through my hair afterwards and a handful a hair comes with it.

To care for these, especially the new ones... for some reason they're tight and kind of hard to get closed and open. For that you need a lubricant with graphite in them and they'll loosen right up. Don't get them wet or they'll rust along with the inside of them.

Mine were in a regular box that I got from a school for us to carry and use our items.
